Any advice please

They are 80 days old and still aren’t finished budding? Something’s gone wrong by the looks of it to me, they should be finished by now. Chop em and toss em.

i would take some scissors and cut the dead parts off, this way you remove those areas and the plants energy can go back to where it should, on the buds. you will not smoke those leaves anyways, you want the buds to be nice, so get your plant looking healthy and cut those off
